In what’s believed to be an unprecedented attempt to bypass the security of Apple iPhones, or any smartphone that uses fingerprints to unlock, California’s top cops asked to enter a residence and force anyone inside to use their biometric information to open their mobile devices.

FORBES found a court filing, dated May 9 2016, in which the Department of Justice sought to search a Lancaster, California, property. But there was a more remarkable aspect of the search, as pointed out in the memorandum: “authorization to depress the fingerprints and thumbprints of every person who is located at the SUBJECT PREMISES during the execution of the search and who is reasonably believed by law enforcement to be the user of a fingerprint sensor-enabled device that is located at the SUBJECT PREMISES and falls within the scope of the warrant.”
